Australia's Cameron Green credited the maiden century of his international career to his seasoned partner at the crease after Friday's marathon 208-run stand with Usman Khawaja against India.

Green hit 114 in his fifth-wicket partnership with Khawaja, who made 180 on a good batting pitch in Ahmedabad on day two of the fourth and final Test.

The middle-order batsman, who returned to the team for the third Test after recovering from a finger injury, took the attack to the opposition but credited Khawaja for his hard grind.

"He's an experienced head that's played Test cricket for more than 10 years now, he's so valuable for guys like myself and a few of the young guys in the team," Green said.

"I'm trying to learn as much as I can off him, and luckily enough there are a lot of guys in the change rooms like that."

Green, standing tall at 1.98m (6 feet and 6 inches), reached his ton soon after lunch with a boundary, earning a hug from Khawaja.

"It's an incredibly tough game, and when you get moments like that you really cherish them," said Green.

He finally fell to off-spinner Ravichandran Ashwin, attempting a sweep that saw him caught behind after the ball grazed his glove.

Ashwin heaped praise on the 23-year-old up-and-comer, who made his Test debut against India in Adelaide in 2020.

"I hope you tuned into the IPL auction, it just tells you how the Indian cricketing fraternity rates Cameron Green," Ashwin said, referring to Green's $2.11 million contract with the Mumbai Indians last year.

"I think he's a fantastic player. Just the raw materials for a person as tall as him, lovely levers, good batting sense, can bowl and really hit the deck well, moves pretty well in the field."
